Insects love warm electrical components and air conditioners are full of them. If you want to keep insects out, experts say do not use insecticides, because the electrical components will not like them. One option is to get a special cover for your relay switch, but be aware that it has to be installed by an air conditioning technician. The cheapest (and easiest) way to keep them away is to use a flea collar. To install the flea collar, shut the power off to the air conditioner and simply placed the collar near the relay switch.
If you have a newer EPA-rated woodstove, you might have a catalytic combuster in there somewhere. Make sure to check the owner's manual about cleaning it - and stick to the schedule. Combusters should last 5 or 6 years, but a clogged or dirty one will fail rather quickly.
Places that are often or always damp can be hard to maintain completely free of mold. If there's some mold in the shower or elsewhere in the bathroom that seems to reappear, increasing the ventilation (running a fan or opening a window) and cleaning more frequently will usually prevent mold from recurring, or at least keep the mold to a minimum.
If your home can't accommodate central air conditioning, try a whole-house attic fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than 25 cents per day to operate.
Remember that extreme temperatures can build in an attic without proper ventilation, especially with a dark colored roof.
Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
Install tight-fitting, insulating window shades on windows that feel drafty after weatherizing.
Energy Star labeled ceiling fans with lighting attached use 40% less energy than conventional models, keeping you cool for less.
Trees that lose their leaves in the fall (i.e., deciduous) are the most effective at reducing heating and cooling energy costs. When selectively placed around a house, they provide excellent protection from the summer sun but permit winter sunlight to reach and warm your house. The height, growth rate, branch spread, and shape are all factors to consider in choosing a tree.
Programmable thermostats are simple, inexpensive devices that provide better savings than any other energy efficiency measure. Available in several shapes and sizes, they can be added to most modern hvac systems and can pay for themselves in as little as a month.
